Study Notes

Wiring and Circuit Requirements

  • Power-limited wiring requirements specified in Part 3 of Article 760.
  • Limitations for power-limited equipment circuits must be verified by a testing laboratory.
  • Underground power-limited copper fire alarm circuits require compliance with Articles 800 (Parts II, III, IV) and 300 (Part I).
  • Suitable cable type for two hours of direct exposure to fire is FPLP-CI.
  • Power-limited circuits may utilize methods defined in Chapter 3, including power-limited and non-power-limited wiring methods.
  • Class 2 conductors are permitted in the same cable or raceway as power-limited circuit conductors without approved separations.

Safety and Installation Considerations

  • The inside of conduits under concrete slabs is classified as a wet location.
  • FPLP cable is allowed to be installed in plenum spaces, while specific riser applications use NPLFR cable.
  • Non-power-limited circuits can be wired using THHN cable in EMT conduits.
  • Failure to remove conduit burrs typically results in ground faults, impacting safety compliance.
  • Exposed non-power-limited wiring requires mechanical protection within seven feet of the finished floor.

System Integrity and Survivability

  • Fire alarm circuit survivability is mandatory for systems employing partial evacuation or relocation.
  • Notifications of emergency alarm circuits need survival integrity, particularly under challenging conditions.
  • Level 3 survivability demands a fully sprinklered building for optimal resilience.
  • Systems designed for total evacuation plans do not necessitate survivability standards.

Mass Notification Systems

  • In-building emergency communication systems are referred to as firefighters' telephones.
  • Mass notification systems serve to issue warnings for various emergencies.
  • Two-way in-building emergency systems also denote reverse 9-1-1 installations.
  • Emergency voice/alarm systems function predominantly through one-way communications.

Inspection and Documentation Standards

  • Fire alarm system installations require comprehensive documentation, including calculations, floor plans, and riser diagrams.
  • Specifications for fire protection systems are contained within Division 28 under the MasterSpec® numbering system, revised in 2004.
  • Standard symbols for fire protection are found in NFPA 170, while standard electrical symbols are found in NECA 100.
  • Documentation must detail equipment specifications, without requiring the name of the equipment supplier on shop drawings.

Special Considerations for Equipment

  • Smoke detectors in elevator lobbies are mandated to be placed within 21 feet of the centerline of each elevator car.
  • Class D circuits are classified as fail-safe circuits, crucial for system reliability.
  • Standards are set for control units in suppression systems, mandating monitoring for alarms, troubles, and supervision signals.

Compliance with Standards

  • NFPA 90A outlines duct detection requirements for HVAC systems, crucial for maintaining fire safety.
  • Physical distances for outgoing and return conductors of Class A, N, or X circuits must be maintained as prescribed.
  • The maximum delay permitted for a waterflow switch is regulated to 90 seconds, ensuring prompt alerting.

General Fire Safety Principles

  • Areas requiring intelligibility for announcements are designated as ADS (Areas of Designated Speech).
  • Power-limited circuits function effectively under voltages up to 600V, governed by tables 12A and 12B.
  • Two-hour rated firewalls require a firestopping classification with a minimum F rating of 120 to block flame passage.
